This is because persistent organic pollutants accumulate in the body fat of living organisms and increase in concentration as they move up the food chain.
<h3>What is Persistent organic pollutants?</h3>
These are organic compounds that are stable and do not degrade easily. They are usually harmful and accumulate in the body fat of organisms.
They are also known to increase in concentration as they move up the food chain which is why predators have more of them.

Photosynthesis provides the ingredients for the mitochondria to perform cellular respiration. Cellular respiration then provides the ingredients needed to perform photosynthesis. And it goes on and on in a cycle
Answer:
The control group consists of elements that present exactly the same characteristics of the experimental group, except for the variable applied to the latter. This group of scientific control enables the experimental study of one variable at a time, and it is an essential part of the scientific method.
Answer:
All the above participate in the ammonia excretion
Explanation:
The amino groups present in the amino acids are required to form the urea. The ammonia disposal takes place un the liver by the urea formation and is excreted in the kidneys by urine. When free ammonia is produced in peripheral tissues, it is transported to the liver by glucose -alanine cycle, alanine in transported in the blood to the liver, where is converted into pyruvate.
Another pathway is by glutamine synthase/glutaminase system. The storage and transport of ammonia to the liver is glutamine from glutamate by glutamine synthetase: NH3 + glutamate → glutamine once in the liver glutamine is transformed into glutamate again by glutaminase enzyme: glutamine → NH3 + glutamate.
In the liver takes place the urea cycle, the amino acids transported into the liver can be converted to aspartate. This aspartate enters the urea cycle forming an intermediate of the cycle, and the final product is urea that is excreted by urine.
